Specification of Letters Patent.

Patented 1%. pr. 13., EH5.

To all 71']! am it may (7(1))(117'7! Be it known that I, Crnns H. Lom'nnn, a citizen of the United States, residing at South Orange, Essex county, State of New Jersey. have invented certain new and useful Improvements in Nut-Locks; and I do declare the following to he a "full. clear. and exact deseription of the invention, such as will enable others skilled in the a rt to which it appertains to make and use the same.

This invention relates to nut locks such as are formed from a. helical segment, and has for its object to stiffen the nut loek so as to increase the resistance which it affords against the clamping elements.

In the accompanying drawings Figure 1 is a plan view of the nut loek-Fig. 2 is an edge elevation of the not lock looking toward the extremities of the segment l ig. 3 an edge elevation of the nut lock when viewed from a point at right angles to that in Fig. 2, and Fig. 4 is an edge elevation of the 'nut lock viewed from a point directly opposite to that of Fig. 3.

Similar numerals of reference denote like parts in the several figures 0f the drawing.

In carrying out this invention portions of the helical segment are bent or displaced transversely on lines that are substantially tangential to the inner edge of the helical or to any imaginary line that is parallel to such edge.

Referring to the drawing, the numeral 1 is used to designate the nut lock generally speaking, 2 designates the inner edge of the helical segment which forms the nut lock, 3 designates the outer edge of such segment, 4 designates the bent or dis laced portions, and 5 designates the line rom which the bending or displacement is effected. The line '5 as it appears in the'drawing is paral lel to a tangent to the inner edge 2 of the segment, but, of course, this bending or displacement might be effected in any desired form. Therefore, it is immaterial as to Where this line 5 is located so long! as it i) substantially parallel with the line h tangential to the edge '2. or. in oth r words, such line must lie sulistanlially at right angles to a illl s of the heliral se nnent. 'lhese bent or d laced portions 4 ar preferably periertiy plain. hut, of rnurse, th l ei'u'ling nm we (lie-ted in su -h mann r that the portions may have rur'red a long as the handing etiertml on a sul stuntialiy tq'ingeu't to ti of the? )('ll(1 l so; line parallel to surh edge.
